for two seconds.
6.3.1 Travel Indication
If enabled, travel indication is displayed in the upper left corner of
the display. The displayed units are the same as programmed in
the
UNITS
parameter. Indicated travel is a relative value. To zero
out travel distance, ensure that the crosshead is not moving, then
press and hold
STOP
for three seconds.
If the cable connecting the crosshead to the rear of the controller is
unplugged, the error message
ENCODER ERROR
will appear. To
clear the message, insert the cable, then press
STOP
.
6.3.2 Limit Switch Operation
Limit switches allow the operator to set a location along the column
at which point the crosshead will stop moving. Limit switches are
located at the rear of the test stand column. Adjust the switches’
positions by loosening, repositioning, and re-tightening the thumb
screws.
6.3.3 Overload Protection
The 09-1143 cable is required for overload protection of a Mark-10
force gauge. If overload protection is enabled, the crosshead will
stop when the programmed percentage of full scale of the force
gauge has been reached.
When overload protection is enabled, if the 09-1143 cable is dis-
connected, and/or if the force gauge is turned off, the error mes-
sage
GAUGE ERROR
will appear. Plug in the cable and/or turn on
the force gauge to clear the message.
Note:
When the crosshead is moving in the UP direction, only the
tension overload setting is active. When the crosshead is moving in
the DOWN direction, only the compression overload setting is ac-
tive.
